概括
缩小背光区直径 (BOZD) 在脊椎病理学 (Ortho-K) 镜头中,在近视儿童中更有效地减缓轴长 (AL) 延长. 定制镜头设计,特别是BOZD和加功率环直径 (PPRD),会影响近视控制结果.
科学领域:
- 眼科医生 眼科 眼科
- 眼镜测量是指眼睛的测量.
- 儿科眼科护理 儿科眼科护理
背景情况:
- 近视的进展与轴长度 (AL) 的延长有关.
- 脊椎病学 (Ortho-K) 镜头设计可能会影响近视控制.
- 了解透镜定制对治疗结果的影响至关重要.
研究的目的:
- 评估透镜定制,特别是后光区直径 (BOZD) 如何影响近视儿童的高阶偏差 (HOA) 和轴长 (AL) 变化.
- 为了评估BOZD,加上电源环直径 (PPRD) 和近视进展之间的关系.
- 调查特定HOA对AL在对Ortho-K治疗的反应变化的影响.
主要方法:
- 对66名高加索近视儿童 (平均年龄13.3岁) 的回顾性研究.
- 孩子们配备了Ortho-K镜头,具有不同的BOZD (4.7-6.0毫米).
- 记录了基线球体等价值和AL;在12个月内跟踪变化.
主要成果:
- 在12个月后,较小的BOZD与较大的BOZD (0.15毫米) 相比,与明显较小的轴延长 (0.08毫米) 相关联 (p < 0.001).
- 在PPRD亚组之间注意到AL变化的差异 (<4.5毫米与>4.5毫米).
- 显而易见的HOA模式出现了:垂直昏迷在PPRD>4.5毫米组增加,水平昏迷在PPRD<4.5毫米组,球形偏差在两者都增加.
结论:
- 在Ortho-K镜头中减少BOZD和PPRD似乎更有效地减缓AL延长.
- 与定制镜头设计相关的光学副作用需要仔细考虑.
- 需要进一步的研究来阐明BOZD,PPRD,瞳孔大小和近视控制功效之间的相互作用.

Power System Distribution
1.1K
Power system distribution involves delivering electrical energy from power plants to consumers through a network of transmission and distribution systems. The process begins at power plants, where energy from coal, gas, nuclear, water, and wind is converted into electrical energy. These plants use three-phase generators, typically rated between 50 to 1300 MVA, with terminal voltages ranging from a few kV to 20 kV, depending on the size and age of the units.

Power Distribution in Three-phase and Single Phase Circuits
631
Power distribution within electrical circuits is a foundational aspect of residential and industrial energy systems. While single-phase power is common in residential settings, three-phase power is the standard for industrial environments with heavy machinery. Each system is different and has advantages, and it's crucial to understand the underlying principles of power distribution and material efficiency.

Axial and Appendicular Muscles
2.7K
Skeletal muscles, the key players in our body's movement, can be classified into two groups based on their location and function: axial muscles and appendicular muscles. These classifications reflect the primary roles the muscles play in the body's structure and movement.
Axial Muscles
Axial muscles, situated along the body's midline, are intricately connected to the axial skeleton, which includes the skull, spine, ribs, and sternum. These muscles facilitate facial expressions and...

Overview of the Axial Skeleton
9.2K
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.

General Case of Eccentric Axial Loading
495
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical...

Meristems and Plant Growth

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.
